David Gregory is leaving NBC after two decades and being replaced on "Meet the Press" by Chuck Todd on Sept. 7. Andrea Mitchell fills in this weekend. CNN and Fox News Channel programs will discuss the changes.

"Meet the Press" been trailing CBS' "Face the Nation" and ABC's "This Week" in the ratings, and Gregory's future had been a topic of speculation for months. "Face the Nation" with Bob Schieffer and "This Week" with George Stephanopoulos generally have offered more compelling fare in recent months.

CNN's "Reliable Sources" will take up the "Meet the Press" changeover at 11 a.m. Sunday. The guests are media critic Jay Rosen, a professor of journalism at New York University; and former CNN D.C. bureau chief Frank Sesno, who is director of George Washington University School of Media & Public Affairs. Brian Stelter is the moderator.

Fox News' "MediaBuzz" also talks "Meet the Press" at 11 a.m. The guests are Lauren Ashburn, David Zurawick of the Baltimore Sun, Jim Geraghty of National Review, Democratic strategist Joe Trippi and Joe Concha of Mediaite. Howard Kurtz is the moderator.

They all will have a lot to talk about because the president of NBC News, Deborah Turness, in April said that reports that Gregory was being dropped were "quite ludicrous." But now she has acknowledged that poor ratings and outside pressure forced the change.

Other "MediaBuzz" topics include unrest in Ferguson, Mo.; the death of Robin Williams; coverage of the crisis in Iraq; and Hillary Clinton's criticism of President Barack Obama's foreign policy.

"Reliable Sources" also discusses Ferguson with the Huffington Post's Ryan Reilly, who was arrested in the Missouri town, and Ash-Har Quraishi of Al Jazeera America.

The program takes up the Rev. Al Sharpton's activisim in Ferguson and his hosting duties on MSNBC. The guests are Crystal Wright, editor of ConservativeBlackChick.com, and Marc Lamont Hill, professor of African-American Studies at Morehouse College.

A 19-year-old Portsmouth woman is facing multiple charges following a police pursuit that ended in Newport News over the weekend and involved two children reported missing in Chesapeake, an official said.

Somebody decided to get cute on Twitter during the recent snow, creating an account in the name of Hampton City Schools Superintendent Linda Shifflette and announcing that schools were closed — before Shifflette had made a decision and tweeted it on her own account.
